As a trained epidemiologist and pediatric intensivist, Dr. Hartman’s research focuses on the delivery and outcomes of health care services for critically ill children in the United States. At the health system level, she is interested in where children with severe illness or injury receive their care and how the cost and outcomes of pediatric care differs by hospital type, region of the U.S., and/or over time. At the individual patient level, she is interested in how critical illness itself affects a child’s developmental trajectory.

Dr. Hartman’s area of expertise is in the use of administrative datasets; she has extensive analytic experience using state-wide, inpatient datasets available from the Healthcare Cost and Utilization Project (HCUP), a division of the Agency for Healthcare Research and Quality (AHRQ). She is also working with Medicare data to develop a comprehensive scale to quantify health state and likelihood of 1-year mortality for Medicare beneficiaries.
